klibc - Aug 2010 - semget() failed

Hello,

	I'm trying to port RPL/2 (http://www.rpl2.net) to OS/2 and I don't 
understand OS/2 semget(). RPL/2 uses POSIX semaphores. I have written a 
minimal library that emulates POSIX semaphores with SysV ones. I have 
tested this library on several Unix systems without any trouble.

	On OS/2, semget() always returns -1 and I don't understand my mistake.

int
sem_init_SysV(sem_t *semaphore, int shared, unsigned int valeur)
{
     int             ios;

     union semun     argument;

     if (shared != 0)
     {
         return(ENOSYS);
     }

     (*semaphore) = semget(IPC_PRIVATE, 1, IPC_CREAT | IPC_EXCL | SEM_R 
| SEM_A);

     if ((*semaphore) == -1)
     {
	// Always true with OS/2 (libc 0.6.3)
         return(EINVAL);
     }

     argument.val = valeur;
     ios = semctl((*semaphore), 0, SETVAL, argument);

     return(ios);
}

	Any explanation ?

	Thanks in advance,

	JKB
